LT1 vs Ls1
Guys have done north of 425rwhp with good heads and cam on a stock shortblock, with untouched intake, so porting the intake on a bolton car should not be worth much if anything.
Roller rockers and good springs would gain you some topend, you could consider a cam that will come pretty close to tapping your budget though.
I would say for an off the shelf though go no bigger than the Comp 503.
I have made fools of a few LS cars at the track, they are more than a little surprised when an LT1 in a whale of a car beats them.
